Basically i set a character with bones and weightmaps and do some aniamtion and save and save all objects. WhenI get close the scene and reloads the mesh is being destroyed by a particular bone and weightmap. I turn weighmap off for particular bone and the mesh is good but not getting previous deformations. Turn it on, it gets destroyed..

any clue whats going on.....

If u on LW 7.5 try to disable faster bones option ...
If u use "Use weight Map only" option make sure that u have weight maps for all bones otherwise if u have even only one active bone without weight map this bon will break all mesh ...
Hove this will help u .

I've had this same problem. I couldn't figure out what was going on with it, but the way I fixed it was I re-did the bone/weight maps for that area.

Thing is
I only need 2 bones for the face.
and they have weight maps assigned.
the rest of the body has no weight maps or bones..... what do u think!

Well try to check the weight map ...
Did my tip (faster bones off) made something ?
Try any options ( u have 3 options to deal with - Faster bones, Use Weight Map only and Weight Map normalization).

In the end of all just try to rebuild these bones and maps :shrug:

Gonna rebuild ...
Before I started this thread I went thru the Bone panel features and deforemation Tab and zilch!


Thanks

Try this: Go through the bones of the rest of the body and turn them off (bone active). You might find that some of the other bones are effecting the mesh of the head. I'm not sure about a fix to this (maybe assigning weight maps to the rest of the body) but it might bring you closer to finding out what is going on.

You cant have JUST a weight map on one part of the mesh. You have to have weight maps on ALL of it even if its just two maps.
More then one bone can share a weight map so you could have a body map and a face map. EVERY bone MUST be assigned to a weight map or you can get funky results. I would avoid using weight map only as it can introduce funkiness. Hope that helps.

This has happened to me twice! It's no joke after spending hours tweaking weight maps, saving and then when you open your file the next morning everything is screwed up!

What happens is certain areas of the model seem to be offset in space, warping and distorting the model. Everything returns to normal when you deactivate the bones that are supposed to affect that mesh area. But when you reactivate them the same thing happens. Turning off weight assignments for bones do not work. I had to resetup the model from scratch in a new scene. :annoyed:

In my case it was these exact steps that caused that particular problem:

I had skelegons in the model
I sent the model to layout.
I translated(moved) the model in z.
I changed the skelegons to bones, I parented bones that
were supposed to be together. Weight maps were already
assigned in modeler.

I then checked deformation made some sample animations. The next day any mesh areas that were in the control of bones that were children in the hierarchy was offset the same distance I moved the model in z from origin. Now I never move the model before I do a setup in layout. Argh. Strangely, rotating the model in y had no effect... Hope this helps.
:hmm:
